1 、绑定DropDownList：
ddl_language.DataSource = createDataSource();
ddl_language.DataTextField = "languageTextField";
ddl_language.DataValueField = "languageValueField";
ddl_language.DataBind();
2、上面用到的createDataSource()方法：
private ICollection createDataSource() { //create a data table to store the data for the ddl_langauge control DataTable dt = new DataTable(); //define the columns of the table dt.Columns.Add("languageTextField",typeof(string)); dt.Columns.Add("languageValueField",typeof(string)); //read the content of the xml file into a DataSet DataSet lanDS = new DataSet(); string filePath = ConfigurationSettings.AppSettings["LanguageXmlFile"]; lanDS.ReadXml(filePath); if(lanDS.Tables.Count > 0) { foreach(DataRow copyRow in lanDS.Tables[0].Rows) { dt.ImportRow(copyRow); } } DataView dv = new DataView(dt); return dv; } 3、Web.config <appSettings> <!--The file path for the language type xml file--> <addkey="LanguageXmlFile"value="d:\Rhombussolution\Rhombus2\Languages.xml"/> </appSettings>4、Languages.xml
<?xmlversion="1.0"encoding="utf-8"?> <languageTypes> <language> <languageValueField>en-US</languageValueField> <languageTextField>English</languageTextField> </language> <language> <languageValueField>zh-CN</languageValueField> <languageTextField>中文</languageTextField> </language> <language> <languageValueField>ja-JP</languageValueField> <languageTextField>日语</languageTextField> </language> </languageTypes>
